Firmly anchored to the cross-bar 23 is ourinternal-combustion power-appliance of which 24 is theinternalcombustioncylinder containing a main: pis'-' ton 25. l The stemz26 of the, pistonextends through a stufling-box 27 in the cyli'nderhead, and is connectedat its outer end with the knuckle, or joint, 28 of upper and lowertoggle-leaves 29, 20. Theupper toggle-leaf 29 1S connected-with an uppercrossehead 30. Extendi gdownward from opposite ends of the uppercross-head are rods 31', 31,=Il10V ablethrough aide-brackets 32, 33,'on'the cheeks. At t eir lower ehd portions the" rods 31 passthrongh a lowercross-head 34. This latter crosshad rests upon collars 35 surroundingthe rods and adjustable thereon by means of nuts '36. Att heir, lowerends the rods bear against cushioningsprings 37. On the cross-head 34,in the positions indicated, are two sets oft-lower briquet-formingplungers 38, 39; respec tively,'each'"set; containing SIX plungers'.

T he lower toggle-leaf 29'is pivotally connected atits end with across-head 40, of the Qiape shown in Fig; 4, through oppositeend-portions of which are openings {fitting aforesaid upper and lowerbriquet-forlning electric motor 64.

loosely around the rods 31. The rods thus piston. On the under side ofthe cross-head '40 are'two sets of upper briquet-forming plungers45,1:46, respectively, there being SIX 'plungers ,',in' each setregistering exact-1y with the lower sets of plungers 38, 39. Thecross-head 40 also carries t ivo sets of ejecting-plungers 47, 48,respectively, in the relative positions indicated, and located withreference to each other the same as the plungers. The ejecting-plungersare of greater length than the briquet-forming plungers, asindicated.

Extending betweep the cheeks-20,21, m a plane between'the cross-heads34, 40, are two supporting frames 49, 50, provided at their ends withou'twardly-projecting flanges 5-1 at which they are firmly secured tothe cheeks. The frames are atopposite sides of the rods 31, and, betweenthe said rods, describesegments'of a circle. The said segmental portionsare provided in their upper sides with V-shaped notches 52 forming thesegments of an annularguide-groove or track.

:33 is a molding-table of disk-shape and provided around its edge withgem-teeth 54. Formed integral with the mold-table, and rising therefromaround its edge-portion, isa rim 55 shaped to present six vertical,segmental sockets 56, equi-distant apart. Extending through the tableare six sets of mold-openings 57, located equi-dismm apart between therim-sockets 56 and disposed with relation to each other, as indicatedinFigs. 4 and 5, to register exactly with the plungers carried by thecross-heads- 34 and 40. Journaled in similar bearing- I brackets 58,toward the upper and lower ends of the cheek 20, is a vertical shaft v595 carrying a mutilated-gear 60 in position to mesh with the gear 54 onthe mold-table, and also carrying a segmental stop 61 adapted to engagethe sockets 56. On the shaft 59. in the position indicated, is an'adjustable cam 62.,and. the shaft also carries, in

the position shown, a worm-gear 63.

Mounted upon the main cylinder 24 is an At the rear .end of the saidcylinder are the two cylinders 65, 66, respectively, of a compressor inwhich work pistons 67 connected witha crank-shaft 68 forming anextension of the armature-shaft of the motor. 1

In Fig. 3 are shown the induction valves having- .cover .and,--beyondthe 69 of the compressorcylinders, the said valves havingclosing-springs 70, surrounding the valve-stems 71 which project belowthe compressor-cylinders. Adjacent to the inductioi'i-valves' are thecompressor-cylinder reduction-valves 72, communicating with a port 73leading to the cylinder 24. Cast upon the side of the cylinder 24 is acontroller-box 7 1 havin a removable cover or face-plate 75. .Core fromthe interiorof the cylinder 24 to the interior of the controller-b'ox isa assage 76 terminating in a supplemental cy inder 77 in thecontrollerbox; 'The'supplemental cylinder contains a piston 78. havin astem 79. F ittingthe cylinder 77 is'a sliding sleeve-piece 80 providedin its end with an adjustable screw 81 carrying jam-nuts 82. Thepiston-stem 79 is guided in the sleeve 80 and is surrounded by aspring-83 confined between the sleeve and piston.

As hereinafter explained, the piston is held normally by the spring 83in the position shown in Fig. 6, being movable therefrom to an annularstop 84 as indicated in Fig. 7. Extending'through thecover 75, andjournailed-therein and in the controller-box is a short shaft 85carrying an adjustablegcam 86 engaging the end of the screw 81. Theshaft 85 extends through 'adial-plate 87 on the said plate, carries aleve1 88. The dial-plate is formed with perforations'89"to receive aplunger 90 on a handle 9-1 carried bythe lever 88. By turning the lever88, and thus turning the shaft 85,'the'cam 86 may be turned to move thesleeve 80 and thereby tension. the spring 83 against the piston 78.

In-the cylinder 24.115 indicated in Fig. 10, is a stationary contact 92of a make-and break electric sparker. Extending from the controller-boxinto the cylinder is a short rock-shaft 93 carrying the movable contact9401? the-sparker. On the shaft 93. in the controller-box; is a finger95. and surrounding the-shaft is a coil-spring 96 which tends normallyto press the finger against a stop 97 inwhich position the parts 92,9-1. are out of contact, as shown in Fig. 10.

The lever is inthe path of the stem 79 of the piston 78 in the movement off-the latterfrom theposition shown in'Figs. 3 and'dto that shown in Fig.

The '120passes thro m "Feathered upon theshafti'120 is a sli upward direction by the engagement of its cam 101with the stop or roller 102, and, as

1t nears the end of its movement, it swings out of engagement with thefinger 95 there by permitting the latter to be returned by its spring tothe stop 97, breaking the spark lug circuit to produce a spark in thewell known manner.

The armature-shaft 104 rotates constantly, in the present construction,and carries a pinion 105 and a bevel-pinion 100. Extending into thecontroller-box, and journaled therein, is a shaft 107 carryii'lg agearwheel 108 meshing with the pinion 105.

109 is an exhaust-valve interposed in the exhaust-passage 110 of thecylinder 21. The

stem '111 of the exhaust valve extends nearly, but not quite, inalinement with the shaft .107, a spring 112 tending to hold theexhaust=valve closed. Loose upon the inner .end of the shaft 107 is adisk 113 formed with a cam 114 working against the end of theexhaust-valve stem 111. The disk 113 carries a rjlliiClhHlQlTlbGI' 115.Feathered upo'n'the shaftlOT is a clutch-member 110 provided with a cam117.. Fulcrumed on a bracketat 118 is a swinging, clutch-shifting,bell-crank arm movable to project into the path of the cam 117 andvhavinga lower arm movable against the clutch-member 116 to slide thelatter into engagement with the clutch-member 115. The 'lower arm of thelever-119 is pivotally connected with the end of the u per arm of thelever 99. The clutch lnecl lever 119 having an upper.

anism described is of a common construcion well known in the art. Whenthe lever 99 is swung, by movement of the piston 78 in the direction ofthe stop 84, the bell-crank lever 119 is swung to raise its upper armout of engagement with the cam 117 and cause the lower arm to slide theclutch-member 110 into engagement with the clutch-menr her 115. "Whenthe levers are swung in the opposite direction, the lever 119 moves atits end into the path of the cam 117, whereby, in the completion of arevoluiion of the shaft 107, the clutch-member'llG is moved out ofengagement with the clutch-memher 115.

Extending-at right-angles to the motorshaft. and journaled in the mainframe. is a countershaft 120 (in Fig. 11') upon which is looselvmounted" a beveLp'iuimi .121 in l mesh with the bevel pinion 100.

and fulcrumed at 127 upon the said bracket is a bell-crank lever 128 ofthe same general construction as the lever 119 before described. Thelever 128 carries a roller 129 to engage the cam 124, and its lower arm'carries a projection 130 to engage and push the sliding, featheredclutch-member 123. On the bell-crank lever 128 is an arm 131. The uppertoggle-leaf 29 carries a bracket 132 (see Fig. 12) equipped at its endwith a spring-plunger 133. Normally, the shaft 120 is stationary, theclutch-members 122, 123 being out of engagement. \Vhen thetoggle-mechanism is flexed, the spring plunger 133, carried by the uppertoggleleaf 29, moves against the arm 131 of the clutch-shippingbell-crank lever swinging the latter to raise the roller 129 out ofcontact with the cam 124 and sliding the clutchmember 123 intoengagement with the clutchmember 122. This causes the shaft 120, withits worm-wheel 12, to be rotated one complete revolution and rotates theshaft 59 and gear60, with its segmental projection 61, one revolution.The parts are so constructed .and'arranged that the engagement-of themutilated gear 60 with the gear 64 of the mold-table rotates the latterexactly one-- sixth of a revolution, and just as this movement of themold-table is completed the segment 61 engages a segmental socket 56 ofthe table and locks the latter firmly against movement.

Mounted against the under side of the cylinder 24 is a sliding frame 134(see Fig. 13). This frame has an arm 135 supported upon swinging fingers136 pivoted at 137 to a stationary part of the pump-cylinder structure.The arm 135 contains a socket 138 through which the lever 99passes nearits lower end; On the frame 134 is an arm or lug 139 projecting beneaththe stems 71 of the pump induction-valves 69. In the movement of thelever 99 from the position shownin Fig. 3- toward the left, the frame134 is slid by thesaid leverjand caused to rise by the swinging fingers136. In this rise of the frame the lug 1 39 engages the valve-stems 71and holds thepump induc-. tion -valves open, thereby preventing thepumps from compressing and discharging explosive mixture into the maincylinder. The frame 1.34 carries a lug'l40 which is in the path of alongitudinally-sliding rod 141 mounted beneath the cylinder. On the endof the rod is a roller 142. engaging the adjustable cam 62 on thevertical shaft '59.

Extending over the mold-table, and terminating at their lower endscloseto the upper surface of saidtables, are feed-chutes 143. Thesediametric'ally opposed chutesare shaped at their lower ends-as indicatedin Fig. 4, each to register with 'a set' of briqueting molds. The chutesmay extend from a material supplying hopper, not shown, and from whichthe material descends by gravity through the chutes t o fill the moldswhen registering therewith.

The operation is as follows: It is to be understood that the feed-tablein each movement is advanced exactly onesixth of a revolution, and,during each pause, twelve of its mold-o )enings register with thefeedchutes; twelve register with the briquetingplungers; and twelveregister with the ejecting-plungers. Initially, the moving parts are inthe position indicated in F igs. 1, 2 and 3. Theconstantly-0peratingelectric-motor actuating the pump-pistons discharges explosive mixturethrough the port 73 into the main-cylinder behind the iston and movesthe latter from the position indicated by full lines in Fig. 6 to theposition indicated by dotted lines therein. In this movement of thepiston the pressure-multiplying toggle-mechanism is extended causing theupper and lower briqueting-plungers to move from the position shown inFig. 14 to thatshown in Fig. 15, .thereby initially compacting thebriquet material. This engagement of the plungers with the briquetmaterial stops further movement of the piston and toggle-mechanism,permitting the pressure behind the piston to be raised by the pumps tothe desired degree. This degree of compression is regulated by theresistance of the spring 83 in the supplemental cylinder 77, the tensionof said spring being governed bythe engagement of the cam 86 with the.screw-extension 81 of the. slidingsleeve. 80. hen the compression behindthe piston 25, and consequently against the supplemental piston 78,exceeds the resistance of the spring 83, the said piston 7 8 is moved tothe stop 84. In this movement it swings the lever 99 from the positionshown in Fig. 3

in the direction to the left, thereby sliding extending the toggle andforcingthe upper briquetingplungers to the position indicated in Fig. 16to produce. the briqnets. It is to be understood that in the initialmovement of the briqueting-plungers, before 'described. the lowercross-head 34 is raised un til stopped by Contact with thestops so" thatunder the forcefof'the explosion the upper briqueting plungers squeezebrique-t material into briquets.

members 115, 116, engage, the disk 113 is turned "by the shaft 107, thespeed of rotation, owing to the ratio of gearing with the motor-shaft,being comparatively slow. The

, parts are so timed that the cam 11 1 is not turned against the stem111 to open the exhaust-valve 109 until the toggle-levers havebeenextended to the'degree desired, which is nearly, but not quite, astraight-line. As soon as the exhaust-valve is opened, pressure escapesfrom the main and supplemental cylinderjs permitting the supplementalpiston 78. to returnto in tial position and turnthe bell'cranklever-119, whereby, as the clutch- ,member 115 reaches the limit of itsturn, the

Theinlet-ports may be tormented" with any suitable mixing-valve orfciirbureter common in the gas-engine art.- When the pump-inductionvalvesareppened and held open, as described, a small amount of-explosivemixture will be simply moved ba'c' and forth. Therefore, there'i's'praticiil'ly no waste of the mixture. As the-force of an explosionin the main cylinder a-g'ainstf the piston 25 depends upon the degree ofcompression of the mixture at the time ofth explosion, the force of the'explosion is easily f" regulated by turning 'the' cam*86 with'reference to the dial-plate'87.

We realize that considerable variation is possible in the details ofconstruction of our improved device without departing from the sirit ofour invention, as defined by the c aims. We do not, therefore, intend tolimit ourselves to the specific construction herein shown and described.Nor do we limit our invention to the employment of a power device inwhich the piston moves, for the reason that it is quite common ininternal-com bastion power-generators, employing a 'piston and cylinder,to have the piston move with relation to the cylinder or to have boththe piston and cylinder move, respectively in opposite directions, undertheforce of an explosion in the cylinder. Since :one form is regarded asa mere reversal of the other, ourinvention contemplates the employmentof either, and the more direct or immediate operate connection of thework-performing member would naturally be with the relatively movablepart or parts, whether the piston, or cylinder, or both.
